Which XPS 15?
gaming wont be stellar for sure since none of the XPS 15 have any discrete GPU and they all use the Intel HD 630 graphics. Also, theres huge variances from model to model for the RAM and CPU so a basic one will be behind the top model using a 7700hq.
If I were you, I would look at something with the upcoming AMD iGPU chips from intel or AMD instead. It will likely be more expensive though.
Intel? Sure. AMD? Oh heck no
The new Ryzen mobile chips with integrated VEGA GPUs are performing better than Intel's.
The last laptop I had came equipped with an AMD A8-6410 that struggled with everything except for web browsing, and checking emails
I am NEVER going back to AMD again
It had plenty of cores, but no hyperthreading and it’s clock speed was really low
It has a 4k monitor but it won't be able to run most games at 4k unless you get one of the more expensive configurations. And since you only play league of legends you won't really need a 4k monitor
I don’t actually have any plans of playing league of legends I was just using that as an example
How good is the Dell XPS 15 9560?
